COLOR-CHART.

To all whom t may concern:

Be it known that I, CHESTER A. YOUNG, a citizen of the United States, residing at St. Joseph, in the county of Buchanan and State of `Missouri, have invented certain new and useful Improvements in Color-Charts, of which the following is a specification,

reference being had therein to the accompanying drawing.

My invention relates to improvements 1n color charts, the objects of which are, first; to provide a simple, substantial and durable chart of this class, in the use of which teachers and others doing art work in colors will-*have a plurality of spectrum colors, secondary tints and complementary tints so pointed out from among other colors and tints that the harmonizing ones can be ascertained by a glance at the chart, second, to provide a color chart bywhich various pluralities of colors and tints which harmonize can be pointed out and used, without being confused with the unused pluralities of harmonizing colors and tints, third; to provide a plurality of complete sets of spectrum colors and their associated harmonious tints, in such order and arrangement, that one set, or the desired parts of two sets of colors can be used, fourth; to so construct and arrange the parts of a color chart, that they can easily and quickly be moved into proper position for pointing out .the desired pluiality of said colors and tints, and to provide yieldable holding means whereby the movable parts of the chart are yieldably held in any desired position, fifth; to provide a color chart which shall'be neat in appearance and be cheap in cost of manufacture.

I attain these objects by the devices ill11 strated in the accompanying drawings, in which Figure 1 is a front view of the chart. Fig. 2 is a sectional veiw in detail, on the line X-X, seen in Fig. 1, looking toward the left. Fig. 3 is a reduced front view of one of the various other forms in which the chart may be made. Fig. 4 is a section similar to Fig. 2, of the parts seen in Fig.v

3. The body 1 of the chart, is made of practically nonelastic cardboard or the like. The indicator disk 2 and the annular mask 3 are rotatably secured on said body by the eyelet 4. I

Tongues 5 are formed integrally with said mask, project therefrom, around Specification of Letters Patent.

rotation in relation to said mask, while the pressure of said tongues against body 1, similarly hold said disk and mask against rotation on eyelet 4, thereby formin frictional holding means for said mas and disk.

Mask 3 has the opening 3 formed therethrough, for exposing to view, the hereinafter described parts of body 1 and disk 2, While the remaining portions of said body and disk are obscured by said mask for avoiding distraction and confusion of the user, as hereinafter described.

The inner marginal line, formed in acirole around and close to the edge of disk 2, is seen at 6, while the outer marginal line 6 is formed concentric'ally thereto. Thev annular space between said marginal lines is divided into three spaces by the intermediate circular lines 7 and 8, the inner one of said spaces being the broadest and the outer one the narrowest of the three. The spacing lines 9 extend from said inner marginal line to said outer marginal line for dividingthe widest concentric space into a plurality of spaces, on which the spectrum colors 10 are applied in sets. Said colors are not indicated by shading, but are pointed out by their initials, one of which is seen at 11. Said initials are R, O, Y, G, B, I, V being the initials of the spectrum colors, red, orange, yellow, greenblue, indigo, and violet, respectively.

The intermediate lines 12 are formed radially between said spacing lines, from said inner to said outer marginal line for evenly subdividing the spaces between said spacing lines into a plurality of smaller spaces.

The secondary tints 13 are formed on body 1, in the intermediate spaces thus formed and are similarly indicated by the green, as the smallest letters V and G indicate. y

It will be understood, that the chart will show a complementary tint composed of certain parts of its component tints, but the user of the chart may exercise his judgment invarying these quantities.

The inner ends oi' all of the radially formed spacing and intermediate lines terminate vin register with the registerpoints 17, which arefornied on the edge portion of indicator disk 2.

Pointers 1S are formed in a plurality of groups on disk l2, or' which one group is seen through opening 3. Said group comprises three pointers, which are shown 1n position, pointing to the initials of the spectrum colors, red, `green and blue, which colors harmonize. The designated one of said-pointers,which points to the red, also points 'toward lthe secondary tint orange, and to the complementary tint which is Y composed of violet andgreen.

Theuser ofthe chart, upon finding that thefcolors and tints thuspointed out, are.

harmonious, uses such quantities of eac-h, as his judgment dictates, in mixing the tints with'thered, for modifying and subduing the glaring effect of `said spectrum color. The central* one of said group otpointers, points-tothe green and toward the blank space iamong the secondary tints, which shows that no tint of this class should be used in conjunction with-the complementary tint of red which is; pointed out.

The other pointer, which points to the spectrum color blue, alsopoints to the secondary tint of indigo and the complementary tint composed 'of green and orange, which should be mixed as previously described.

Other combinations o `hai-monious tints and colors are pointed out in the following manner: rllhev-user of the chart holds the masknagainstrotation, by applying his finger to the edge of it, and with af inger'of the 'other hand, passed through opening 3', he rotates disk 2 in the direction and as many steps as he desires for bringing pointers 18-into the idesired position,with register points 17 inregister with the inner ends of lines 9 and 12, after which vhe consults the f chart vfor lascertaining therefrom the spectrum colors and tints which harmonize, as previously described.

Fractionalparts of two-groups of -spectrum colors and their tints are used inthe follow-ing manner:

The user of the chart rotates mask 3 in are-exposed through opening 3,after which he rotates disk y, until the pointers V18 point toward the desired spectrum colors and toward the desired ones of their secondary and complementary tints, which are so arranged and spaced that the ones thus pointed out are harmonious, regardless of 'the ones to which the group of pointers 18 (which also are properly spaced to perform theirfunc-tions may point.

When it is desired, a greater or less number of harmonious spectrum colors than the described three are pointed out in the `following manner:

The user of the chart'holds mask 3 against rotation by the edgethereof and passes the iingers oi' his` other 'hand through opening 3 `and by the edge oi disk 2 -he rotates the samein .either direction, until the desired one of thegroups of pointers 18 is thereby moved into view through said opening. He then rotates `said disk -and mask until they arein the desired-position for pointing out the desiredspeetrum colorsand theirassociated tints.

VVhile'I have shown and described my invention as beingprovided-with four sets of spectrum colors and a like number of groups oi'pointers,litis evident that any desired plurality of sets of said colorsandany number of groups. oifpointers could be provided, and Aalso*thatvcharts could be made :orl the useof primaryv pupils, in which either the secondary or ythe complementary tints or both are omitted, lwithout departing :from ther-spirit of my invention, all` otwhich I reserve the. right to do.

One ofsuch other forms of charts is shown in Figs. 8 Yand-4, in which the indicatordisk 2 isomittedand the-mask-lt) is mounted on body Vf 1. `Said mask lhas the opening 19 ormedftherethrough, for exposing Zone set of-spectrum colors 10, and has the group of pointers 20 'formed thereoinfor pointing to acertain number of-saidr colors which harmonize. Saidfmask is. rotatable on leyelet Af, or'permitting said maskr and the thereon carried pointers- `to be moved into register with variouslharmenizing yones `of-said colors.

Having fully `'described my invention, what claim as new and desire to secure'iby LettersPatent is l. Achart body; :an indicatorr disk rotatably mounted over the central portion-fof said body; an inner, circular, marginal line 'formed on-said -bodyadjacent-to the edge'of saidfk disk; anouter, circularl marginal' line formed on said body; two intermediate lines formed" on said bodybetweensaidmarginal lines, forming three concentric -spaces on said bodyaround:said-disk; theinner one of said spaces. being the broadest fand the outer one being the narrowest of said three spaces; spacing lines formed radially `across said spaces for separating ysaid inner concentric space into a predetermined plurality of spectrum spaces plural-itylotsetsof spectrum colors formed on'said body in said `spectrum spaces; indications formed on said spectrum colors whereby the name of each color can be determined; intermediate lines formed radially between said spacing lines which together with the latter evenly divide the intermediate and outer concentric spaces into a plurality of intermediate and outer spaces; secondary tints formed on said body in said intermediate spaces; complementary tints similarly formed in said outer spaces; sec` ondary indications for indicating the colors of which said secondary tints are composed; complementary tints similarly formed in said outer spaces; complementary indications for indicating the colors of which said complementary tints are composed; a rota* tably mounted group of pointers for pointing toward the colors and tints which harmonize; and register points similarly mount ed with said polnters whereby said pointers have their proper positions determined.

2. In a color chart, the combination with a practically non-elastic chart body and two superimposed elastic disks rotatably secured on said chart body by a pivot through their centers; of a plurality of tongues formed with the outer one of said disks, said tongues extending from said outer disk between said chart body and the marginal portion of the intermediate disk, forming rictional holding means whereby said disks are yieldably held against separate rotation and whereby the outer one of said two disks is similarly held against rotation on said pivot.

In testimony whereof I aiiix my signature.
